Watt Charging Speed
A charging-session estimator deriving battery-input watts from percentage changes and capacity assumptions.
Consider for rough same-device charger comparisons
Labeled sessions and range-based benchmarks support repeatable informal tests.
Keep in mind: It cannot read hardware power directly. First results may need ten percent charging; screen load, temperature and capacity assumptions affect estimates.
